Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a vehicle getting on/off device, and more specifically, a device for a vehicle that is installed in a vehicle so that a physically disabled person who uses a wheelchair can ride and drive the vehicle while in a wheelchair. This relates to a boarding device.

Prior Art Conventional riding devices for physically disabled persons include:
There is Japanese Unexamined Patent Publication No. 58-54954.

However, this device has the following drawbacks because the entire wheelchair is placed inside the vehicle.

That is, (a) the platform simply rotates, and when it stops at the wheelchair loading position, the hydraulic drive device built into the wheelchair is operated by operating a manual pump, and the platform abutting wheels are activated for the first time. The wheelchair is used to get off onto a platform, and requires operating means that are difficult to adjust to the platform and wheelchair, and therefore cannot meet the need for quick boarding.

(b) If the lower part of the wheels of the wheelchair is not raised to a position higher than the upper edge of the door threshold, and the footrest is not raised to a position above the platform, the wheelchair will collide with the platform when turning, so this operation is essential. Similarly to (a) above, this cannot meet the need for a quick ride.

Also, (c) since the platform is rotated manually, is it impossible for a passenger seated on the platform in a wheelchair to rotate without an attendant?
Otherwise, the task becomes extremely difficult.

(d) When the platform stops at the wheelchair loading position, the vertical height of the platform will depend on tire pressure, weight of loaded items, etc. If the overall height of the vehicle is high, the platform will be at a high position, and if it is low, the platform will be at a low position. It will become a prominent position. Therefore, the adjustment allowance for the vertical height of the wheelchair itself will also differ each time the user gets on the wheelchair.

OBJECTS OF THE INVENTION In view of the prior art, it is an object of the present invention to make it possible to quickly get into a car and to eliminate the need for fine adjustment of the platform.

Then, the slider support frame 40 is placed on the seat support frame 31 and fixed with the tightening screws 42 to assemble the wheelchair. Further, locking pins 43 are provided on both sides of the slider support frame 40, as shown in FIG. An arm 44 is provided.

Next, the action will be explained.

The process up to when a physically disabled person M riding in a wheelchair 30 is seated in the driver's seat position of the automobile 1 will be described.

A pair of seat pedestals 18, 18 are provided at the position of the driver's seat on the floor 2 of the automobile 1. They are arranged as shown in Figure 7.

Then, the physically disabled person M in the wheelchair 30 opens the front door FD and the sliding door SD, and while riding in the wheelchair 30, grabs the switch box 54 that is within reach inside the vehicle and holds it in his hand to operate the vertical movement. Operate the switch 55 so that the arm 8 rotates upward. At this time, the cover 52 provided on the seat support base 16 is rotated to cover the magnetic proximity switch 50, and the magnetic proximity switch 50 is placed in the operating state. When the magnetic proximity switch 50 is operated, the vertical operation switch 55
and the turning operation switch 56 are set to an operable state.

When the vertical movement operation switch 55 is operated to rotate the arm 8 upward, the motor 12 rotates, the hydraulic pump 11 is driven, and oil flows into one end of the cylinder portion 10a of the vertical hydraulic cylinder 10. Then, the cylinder rod 10b moves and rotates the arm 8 upward. As the arm 8 moves upward, the seat support base 16 also moves upward. Then, when the arm 8 moves upward to a predetermined upper limit position, the vertical movement operation switch 55 is stopped to stop the upward movement of the arm 8.

Next, the turning operation switch 56 is operated so that the arm 8 turns to the right from the driver's seat position to a position outside the vehicle. When the swing operation switch 56 is operated to swing the arm 8 to the right, the motor 12 rotates again and the hydraulic pump 11 is driven, and at this time, the hydraulic circuit (not shown) is switched to rotate the cylinder portion 9a of the horizontal hydraulic cylinder. Oil flows into one end of the cylinder rod 9b, and the arm support member 7 to which the arm 8 is pivoted rotates clockwise, causing the arm 8 to pivot to the right. Then, when the arm supporting member 7, that is, the arm 8 has turned to the right by 110 degrees to a predetermined right turning position, the operation of the turning operation switch 56 is stopped, and the right turning of the arm 8 is stopped. thus,
The seat support base 16 provided at the tip of the arm 8 is moved from the driver's seat position to the outside position of the vehicle, as shown in FIG.

After the seat support base 16 has been moved to the outside position, the vertical movement operation switch 55 is operated again so that the arm 8 moves downward from the upper position to the lower position. When the vertical movement operation switch 55 is operated to move the arm 8 downward, the motor 12 rotates and the hydraulic pump 11 is driven, and oil flows into the other end of the cylinder portion 10a of the vertical cylinder 10. Then, the cylinder rod 10b is retracted and the arm 8 is rotated downward. Then, when the arm 8 moves down and the seat support base 16 provided on the arm 8 moves down to a predetermined lower limit position where it can receive the seat 3 of the wheelchair 30 as shown in FIG. 9, the vertical movement operation switch is turned on. 55 is stopped and the downward movement of arm 8 is stopped. At this time, the lower limit position of the seat support base 16 is at a height slightly lower than the bottom surface of the seat 3 of the wheelchair 30.

When the seat support base 16 is set to the lower limit position outside the vehicle, the cover 52 is removed from the stopper 52a and rotated so as not to cover the magnetic proximity switch 50, and the magnetic proximity switch 50 is put in the inactive state and the seat is moved up and down. The operation switch 55 and the rotation operation switch 56 are set to an inoperable state in which they do not operate even if the operation switch 55 and the rotation operation switch 56 are operated, so that the seat support base 16 is prevented from moving unexpectedly.

Thereafter, as shown in FIG. 10, the physically disabled person M riding on the wheelchair 30 operates the operating ring 33 to move the wheelchair 30 backward with respect to the seat support 16 so that the bottom surface of the seat 3 is directly above the seat support 16. Move it to position. When the slider support frame 40 of the seat 3 is located directly above the seat support base 16, the magnet 51 provided at the rear of the seat 3 moves the magnetic proximity switch 5 as shown in FIG.
0 and activates the magnetic proximity switch 50. By operating the magnetic proximity switch 50, the vertical movement operation switch 55 and the swing operation switch 56 are set to an operable state again.

Next, after loosening the tightening screw 42 of the wheelchair 30 and setting it so that the seat 3 can be removed from the seat support frame 31, the vertical movement operation switch 55 is operated so that the arm 8 moves upward from the lower limit position to the upper limit position. to move arm 8 upward. When the arm 8 moves upward a little, the seat support base 16 moves upward accordingly, lifts the slider support frame 40 of the seat 3, and removes the seat 3 from the seat support frame 31. At this time, the positioning arm 44 provided at the rear of the slider support frame 40 fits between the boom 15 and the locking protrusion 16a provided at the end of the seat support base 16 on the boom 15 side, and the seat 3 is supported while being positioned at a predetermined position on the seat support base 16. Therefore, as will be described later, even if the seat support base 16 moves, the seat 3
will not fall off the seat support base 16.

After that, as shown in FIG. 11, while sitting on the seat 3 supported by the seat support base 16, the seat support frame 31 is removed from the position directly below the seat support base 16, and the wheels 34, Armrest 35, footrest 3
7. Remove the casters 36, disassemble the wheelchair 30, and store these parts inside the vehicle. Once you have finished storing the parts, turn the vertical operation switch 5 again.
5 to move the arm 8 upward, and when the arm 8 moves upward to a predetermined upper limit position, the vertical movement operation switch 55 is stopped to stop the upward movement of the arm 8.

Next, the turning operation switch 56 is operated so that the arm 8 turns to the left from the position outside the vehicle to the driver's seat position. When the swing operation switch 56 is operated to turn the arm 8 to the left, the motor 12 rotates again and the hydraulic pump 11 is driven, and oil flows into the other end of the cylinder portion 9a of the horizontal hydraulic cylinder 9, causing the cylinder rod to rotate. 9b retreats, and the arm support member 7 to which the arm 8 is pivotally connected rotates to the left to support the arm 8.
turns left. When the arm support member 7, that is, the arm 8 has turned to the left to a predetermined left turning position, that is, to the driver's seat position rotated by 110 degrees, the turning operation switch 56 is stopped to stop the arm 8 from turning to the left. At this time, the arm 8 is at a predetermined upper limit position.

In this way, the seat support base 16 on which the seat 3 is placed, which is located outside the vehicle, is turned to the left and set to the driver's seat position. position to move the seat support base 16 downward. The seat support base 16 moves downward while moving slightly toward the front of the vehicle to a predetermined seating position.
A pair of seat pedestals 18, 1 provided on the floor 2
When the slider support frame 40 of the seat 3 is placed so as to straddle the seat 8, the vertical movement operation switch 55 is stopped to stop the downward movement of the seat support base 16. At this time, the seat support stand 16 is located between the pair of seat support stands 18, 18, and the slider support frame 40 of the sheet 3 is placed on the seat support stands 18, 18 so as to straddle the slider support frame 40. The front end of the slider support frame 40 is locked to a seat locking piece 20 provided at the front end of the seat holder 18 located at the center of the floor 2, but the rear end of the slider support frame 40 is not locked. Therefore, the seat 3 may move toward the rear of the vehicle. Therefore, the operating lever 26 is operated to rotate the locking hook 22 toward the front of the vehicle, and as shown in FIGS. The seat 3 is fixed in the driving position so as to prevent movement of the vehicle in the longitudinal direction. Further, movement of the seat 3 in the width direction of the vehicle from the driver's seat position is performed by a seat stopper plate 19 and a seat locking piece 20. Therefore, the physically disabled person M sitting on the seat 3 in the driver's seat position can drive with peace of mind.

The above has been described until the physically disabled person M riding in the wheelchair 30 sits in the driver's seat of the car 1, but when getting on the wheelchair 30 from the car, it can be done by following the steps in reverse to the above. can.

Effects As explained above, according to this invention,
Its structure is such that a lifter is disposed on the floor of the vehicle and has an arm that pivots between a position outside the vehicle and a driver's seat position and moves up and down, and a seat support base that supports the seat is provided at the tip of the arm. Therefore, by preparing a wheelchair with a removable seat, the wheelchair can be moved so that the bottom of the seat is directly above the seat support base located outside the vehicle, and then the arm can be moved slightly upward to allow the user to move the wheelchair. The seat on which the disabled person is sitting is removed from the wheelchair and supported on the seat support base, and then the arm is moved up from the outside position of the vehicle, then swiveled to the driver's seat position, and lowered from the driver's seat position to the seating position.
